To all 'whom'it may concern:

Beitknown' that I, WILLIAM R. Knivwann, a citizen ofthexU-nited States,residing at Airtelhin the county of Marshall and State a of Kansas, haveinvented a new and useful HuskingQ/Iachine, of'which the following is aspecification. i a

This invention relates to husking machines, it being morejparticularlyan attach-' inent adapted to be placed on a wagon or other yehicle,means being provided whereby the husking mechanism can be driven by oneor more Wheels of the vehicle to which the structure is attached. 1

A further object is to vprovide improved means for husking the corn,said means including a novel arrangement of husking rolls and means forconveying theears positively alongthe rolls so as to discharge themlflltimatelyfinto an elevator provided there or. c 1

A further object is to provide means for collecting the loosegrainsofeorn anddirecting them into the elevator so'that they will bedischarged into the vehicle with the ears of corn. i y With theforegoing and other objects in view which will appear as the descriptionproceeds, the invention resides in the combination and arrangement ofparts and 1n the details of construction hereinafter described andclaimed, it being understood that changes in the precise embodimentofthe invention herein disclosed, can be 'made within the scope of whatis claimed, without departing from the spirit of-the invention. i t. r

Referring to the figures by characters of reference A designates thebody or box of a vehicle having the usual supporting wheels B. Asprocket 1 is adapted to be bolted or otherwise secured to the innerside ofone adapted to be secured to the inner side of v the other wheelB. Secured to the running gear of the vehicle in any suitable manner,

here being shown extended under the body A whlle the upperarms areextended along the sides of the body, both arms being attached to thebody by suitable straps 4: extended under the body and across the framemembers and then hooked into engagement with the upper edges of thesides of the body A. This structure has been clearly shown in Fig. 3. y

The two frame members 3 carry the mechanism constituting the presentinvention. These frame members are connected,

back of the body A, by a cross beam 5 on of the wheels B while anothersprocket 2 is are side frame members 3, preferably U-' shaped, the lowerarms of the frame memthe end portions of which are journaled H verticalshafts 6 and 7 respectively, eachof these shafts carrying a sprocket 8and the two sprockets being engaged byan endless conveyer belt 9 whichcan be in the form of a chain, there being outstanding fingers 10 ofcorn to be acted upon; The flights of the conveyer extend transverselyof the machine and back of the body A, the forward flight being closeto'and parallel with a husking roll 11 mounted in bearings 12 supportedby the frame members 3. i

Thefingers on the forward flight of the conveyer extend over the huskingroll 11, as shown in Figs. 1 and 2 and the husking roll 11 isprovidedeither with longitudinal corrugatlons or with spiral rlbs, as preferred,this roller receivlng motlon from intermeshing pinionsll' one of whichis mounted on "upon the conveyor belt at distances apart slightlygreater than the length of the ears the shaft of the roll 11, the otherof which (see Fig. 9) is carried by a shaft 100 supported in anyappropriate manner uponthe frame of themachine, the shaft 100 having asprocket wheel '18 receiving a chain 17.

The chain 17 extends' forwardly along one side of the body A and ismounted, at its frontportion, upon a sprocket 19 carried by the shortarm 20. of a bell crank lever 21,

the long arm' of this lever-being extended upwardly beyond the Side ofthe-body A so" as to be manipulated conveniently. .7 This long arm oflever 21 can be locked in any suitable manner so as to be held againstmovement and when sprocket 19 is in its lowermost position, the lowerflight of chain 17 is held in engagement with the upper portion ofsprocket 1 so that, as the wheel B rotates, the chain 17 will beactuated and motion thus transmittedto the roller 11.

The roller 11 1 drives a second roller 13 which is journaled in bearingblocks 14 slidably mounted in guides 15. The surface'of roller 13 isformed of rubber or other suitable soft material designed to friction- Aally engage the roller 11' and springs 16 bear against the blocks 14 soas to press roller 13 yieldingly against roller 11 at all times. The.roller 11 therefore constitutes the means for driving the roller 13 andin turni s adapted to be driven by the chain 17 which engages thesprocket 18 secured to the shaft 100. Another roller 22 issupportedabove and normally contacts with the roller 13, this roller 22being jonrnaled in bearings 23 carried by supporting springs 24, thesprings being so arranged as to press roller 22 yieldingly againstroller 13. Roller 22 is preferably provided with a soft periphery madeup of rubber or other suitable material designed to .frictionally engageroller 13 so that, during the rotation of said roller 13, the roller 22will be actuated. The direction of rotation of the various rollers hasbeen indicated by arrows in Fig. 1. An

arcuate shield 25 is arranged to bridge the space between the rollers 22and 11, there beinga sufficient space between this shield 25 androller11 to receive the fingers 10 of the c'onveyer 9;

A trough 26 is supported under the rollers 11, .13 and 22, this troughbeing inclined downwardly'toward one side of the machine and beingprovided, at its top, with a grate 27 on which the husks and any loosegrains .of cornare adapted to fall from the rollers of the :huskingmechanism. The grate is so 7 inclined that the husks will-slidetherefrom causing the material to move upwardly to an outlet spout 31which extends from .the

upp.er. end of thecasing 28 and discharge into the body A. I Anotherspout. 32 extends fromnnder the rollers 11, 13 and 22 at one,

end andnserves to direct the ears of corn from the ends-of-the.rollersinto the elevator casing 28l Thus ;it.- willbe seen that the; elevator29 serves not only to lift the loose grains of corn up to the spout 31but also to lift the husked earsto said spout; The V elevator 29 isdriven. by novel mechanism provided for that purpose. The said mechanismincludes a shaft 33 onwhich thelelevator 29 is mounted, this shaft beingpro- ;videdwith a gear, constantly meshing with another smaller gear 35secured to a shaft 36. Said shaft 36 has a sprocket" 37 secured theretoand engaging thesprocketiis' a drive chain 38 engaging a sprocket39021.1.- ried by a bell crank lever 40. One arm of this bell cranklever is connected by a rod l1 to a shifting lever 42fulcrume'dzu'ponone side of the body A, any suitablemeans being providedfor lockingthisleverjagainst movement: It willbe: apparent thatawhen theshiftinglever isinoved. in one direction,

sprocket 39 willbe shifted doWnwardly-,-thusi bringing the lower flightof chain 38 into engagement with the sprocket 2 so that, as the vehiclemoves forward, motion will be transmitted from sprocket 2'to chain 38and thence to shaft 36 and, thro'ughxgears 35 and 3A-t0 shaft 33 andelevator 29; By shiftinglever 4:2 in the-opposite direction,

however, the chain 38is.lifted out of en gagement with the-sprocket 2and the operation of the elevator is thus stopped.

A sprocket 43 rotates with shaft 33: and is engaged by achain 4A which,in turn,flengages a sprocket l5 secured 'to a shaft/'16 which isjournaled in one of the frame members This shaft 456 has a bevel gear 47which meshes with another bevel gear 48 secured to the lower end-ofshaft 7; Thus it will be seen that as longas the elevator -29 is inoperation, motion will be'transmitted to the conveyer' 9 whichreceivesits motion from the shaft 7. I

In order that the-husking rolls may} be properly supplied with ears forhuskin'g, a

delivery spout 46 is fixedlymounted on one.

of the frame members '3 and extends upwardly and laterally therefrom. Atrans?- verse shaft is; extendedlaterally from this? shout, as shownat47Land hasa sprocket 48 secured to it and receiving? motion through achain 49, from a sprocket 5O which rotates with thenshaft' 100. Shaft47' has an elevator casing 51 hungtherefrom and mounted in this casingisan ele vator- 52 extending downwardly, and .for-* wardly. The lowerend ofthe elevatorcas ing is supported by a lifting, rod; 53 connected,as-by: means of a link 54, .toone. arm 3 55 of a bell crank lever 56,the other arm of the bell crank lever being extended abovev the body Aandv provided with any suitable, n eansl wherebyit' can be.- lockedagainst movement. Obviously by means of .this lever 56 thelower end.ofthe-elevator casing .can be swung upwardly orfldown wardl'y' so; asto be brought .to any 'desired distance;

1,1 mess;

from the ground. Arranged along the outer side of theelejvatorcasing 51are snapping rolls 5'7 and.58,} respectively, the roll,58 be- That,portionof the elevator casing 51 at one sideaof therolls 57 and 58 iscut away so that thecorn when snapped from the stalk will be free tofall laterally from the rolls and onto the elevator 52. Gatheringfingers 60 diverge from the lower ends of the rollers, as shown in Fig.3 and operate as ordinarily to collect the stalks so that v they .willbe fed into the pass between the snapping rolls 57 and 58. The twosnapping rolls rotate in opposite directions, this being due to the factthat each of themlias a ear 61 at its u oer end the two ears b 7 bmeshing. One of thesnapping rolls 58, has a shaft 62 extending upwardlytherefrom and provided with bevel gear 63 which mesheswith a gear 64.secured to shaft 17.-

From the'foregoing description it will be apparent that when the machineis drawn. forward and-'thel chains 17 and 38 are in 1 engagement withtheir respective driving sprockets, motion will be transmitted to thevarious parts of the mechanism. Thusthe stalks will be directedintothepass between the snapping rolls 57. mass and these rolls, which can beeither corrugated, plain, or formed with spiral ribs, will engageothestalks and breakthe ears therefrom, The cars will. be shifted laterallyby the rolls57 and 58 so as tofall onto the elevator 52 which elevatorwill carry them upwardly and discharge them into the spout 46T and thisspout, in turn, will direct the ears onto the feeding endsof thehuskingrolls. The rolls 11 and 13 will cooperate to remove the husks from theears" and direct the husks downwardly onto the grate 27. During this.actionf'of the rolls 11 and 13 the fingers on the conveyer 9will engagethe ears and drag them longitudinally ofthe rolls, the rotating roll 22serving to maintain the ears in position between. the fingers 10 on thecon veyer. When the ears reach the discharge ends of the husking rollsthey are directed into the spout 32 and thence onto the elevator 29which carries themto the wagon body in the manner hereinbeforedescribed. It has been found that by providing a conveyer in connection.with husking rolls such as disclosed, the operation of removing the huskis more efficiently performed than where the ears are shifted along therolls solely by gravity. Furthermore by utilizing one husking roll whichis operated solely by frictional engagement with the other'huslc ingroll,the first named roll is free to stop rotating should the earsbecome wedged be tween the rolls and, consequently, danger of *roll 63.

crushing the cars is reduced to the mini-:

. Instead of driving the husking rolls in the manner hereinbeforedescribed and as illustrated in Fig. a, .mechanism such as llustrated inFig. 6 can be utilized. By referring to this figure it will be seen thata husking roll 61 is driven as before described,

and frictionally engages the husking roll 62. This husking roll isdriven frictionally in the manner hereinbefore described but a worm 63rotates therewith and constantly meshes with a worm gear 641 secured toa shaft 65. Thls shaft 1s Journaled on an arm 66 which is fulcrumed onthe shaft 67 of roller 62, and a bevel gear 68 rotates with shaft 65 andmeshes with another bevel gear 69 secured to a shaft 70 journaled inthearm 66. A sprocket 71 rotates with shaft 70 and transmits motion througha chain 72 to a SPl'OCh'Gt 73 which is connected to the roll 7 1, saidroll being journaled in an arm I T5 formedintegral with or fixedlyconnected to thearm 66. Thus it will be seen that by shifting arm 75 theroll 74: can be adjusted toward or from the roller 61 without, however,disturbing the mechanism employed for transmitting motion from roll 62to the In this modified form a shield 76 similar to the shield 25 isextended from thearm 75 so as to bridge the space between the rollers 61sand73.

Importance is attached to, the fact that the I mechanism hereindescribed can be applied readily to a wagon alreadyin use and by drawingthe wagon along one side of a row, the corn growing in the row will bequickly and efficiently gathered and husked, the husks being dischargedonto the ground and the ears directed into the body of the wagon. It isto be understood that the roller 22 shown in Fig. 4, can be adjustablymounted on the spring 2 1 by providing longitudinal slots 24 in whichthe bolts 23', which secure bearings 23 to the springs 24, can beadjustably mounted.

By referring to the seen that the husking rolls 11 and 13 form thebottom of a trough the sides of which are made up of the roll 22 and theconveyer 9 respectively. p

In Figs. 7 and 8 the parts remain as shown in Fig. 6, correspondingparts being designated by the same numerals with the suflix a. In thisform of the invention, a spiral roller 101 formed in one or moresections and supported in any convenient manner upon the frame work ofthe machine, coacts with the ear of corn E to advance the samelongitudinally of the rolls 7%, 62 and 61.

The roller 13, being covered by a facing of rubber or the like, gives acushioning grip on the husk, when used in connection with the corrugatedroller 11.

Attention is called to the fact that the drawings. a will be shieldwhich bridges the space over the husking rolls 11 and 13 is for thepurpose of preventing the ears of corn from being thrown upwardly awayfrom the husking rolls while the rolls are stripping/the husks from theears of corn. In other words the ears of corn are held down on thehusking rolls and the ears are caused to rotate while being movedlongitudinally, this rotation being facilitated by roll 22 so that allof the husks will be removed from the ears.

The ears are under absolute control at all times while being conveyedalong the husking rolls.

What is claimed is 1. A husking machine including a receptacle forhushed corn,- an elevator at each side of the receptacle, and huskingmechanism extended between the elevators, one of said elevatorsconstituting means for elevating ears to the husking mechanism and theother elevator constituting means forconveying husked ears to thereceptacle, the husking mechanism and the elevators being supported bythe receptacle.
